Can a Lewmar #43 replace a #40?

Hi All...

I have been unable to find mounting specs on a Lewmar #43ST. Can one of these replace a standard #40 int he same mounting holes?

Thanks...

Jim

TBH< I would swag no! As I believe the units are different diameters. If they have the same diam base, then it is quite possible. Is there a store near you that carries the items? if so, go look and measure. "THEN" the issue becomes, the 40's on you boat may be 6 1/4" bolt fastened, the new ones 5 5/16" bolt fastened! so even going from std 40 to a ST40 may cause some issues.

Hi Marty, actually Lewmar's web site has identical mounting instructions for the #40 and the #40ST, which are:

5 x M6 (1/4 in) csk head screws on 121mm (4 3/4in) PCD.

I can't find any info on the #43STs though...

Well at least my potential bad issue is not really bad!

Not sure what to say on the 40 vs 43's tho. 'm going to swag no until further figuring out. Too bad the winch maintenance class I took a the local WM with the lewmar rep was last wednesday, I could have asked this wedesday evening for you!

"Mounting Instructions 5 x M8 (5/16 in) c’sk head screws on 136mm (5 11/32 in) PCD. Lewmar recommend that the rope enters onto the drum at an angle of 5 to 10 to the base axis of the winch. To achieve this angle it may be necessary to use a base wedge when installing the winch. This product is Made to Order."

Those are the specs for a 46ST, i could not find any info on a 43, which leads me to believe, that winch you are looking at is not made or some other equal! But the 46 is bigger in diam than the 40's are! Which leads me to believe the 43's, assuming you are finding those used, would also be a bigger diam circle!

Looking some more at lewmars site, the newer 44 non tailing has teh same bolt config as the 46st, so it might be that the 43, not made is the same as the 44 and 46 sized winches, ie again as I swagged, bigger than a 40!

Thanks Marty, the #43 is sure bigger than the #40, but not by much so i was wondering if the mounting configuration might be the same. I'll keep digging but if i had to guess i would say it is not, just because

Jim,
Doesn't look like it, different part numbers from the schematics. Call pyacht though, they should be able to give you a definite answer.

Can a Lewmar #43 replace a #40

The #43 Lewmar is a standard winch (non self tailing), to the best of my knowledge, there is no #43ST (self tailer). I am replacing a Lewmar 40 with a #46ST, and the mounting holes are different. Anywhere I went with the biggest unit I could fit taking into account my grey hair factor.

Well I have seen pictures of what were claimed to be #43ST winches, but now I am wondering if someone made a mistake. I'll ask him to double check, but I do agree its odd that I can not find any specs on these. I am starting to agree that maybe they don't exist.
